[ARCHIVED] Citywide Utility Check

The City of Key West is teaming up with USSI to test the integrity of sewer lines citywide. Beginning July 14th, crews will begin smoke testing. They will put hang tags on the residences of the area they are working that clearly explain the process.

The test consists of forcing safe, vegetable oil derived smoke into the sewer lines and observing where it escapes in order to determine any location of leaks or defects.

Odorless and safe, the smoke leaves no residuals or stains and has no adverse affects on people, plants, or animals.

The smoke will be visible coming out of manholes and sewer vent stacks on rooftops. It should not come into buildings. However, the City recommends pouring two or three gallons of water into sinks and floor drains that are seldom used to ensure there is water pressure to keep the smoke out. However, if some rises into a building, it is harmless and will dissipate quickly.

Residents do not need to be at home during the testing, and each test takes about 15 minutes. If you do have questions during the test, the uniformed crews outside are happy to answer questions.

The vapor dissipates in about 10 minutes, and the City will know if and where there are any problems with our sewer line. Testing the entire island is expect to take about three weeks, weather permitting.
